$MGIC 3 Month Trend breakout

I am looking to enter $MGIC a low volume speculative play on the next high around $7.51. I have a stop loss of $6.81 to be set upon entry and hope for continuation of the trend breakout. Volume will make this a tricky position. Stop may not be wide enough, but based on the 20 Day ATR it looks to be a safe bet based on my systems approach to trading.
